Potassium hydroxide (chemical formula: KOH, amount: 56.11) white powder or flaky solid. Melting point of 360 ~ 406 ℃, the boiling point of 1320 ~ 1324 ℃, Potassium Humate the relative density of 2.044g / cm3, flash point of 52 ° F, refractive index n20 / D1.421, steam pressure 1mmHg (719 ℃). With strong alkaline and corrosive. Easy to absorb moisture in the air and deliquescence, absorption of carbon dioxide from potassium carbonate. Dissolved in about 0.6 parts of hot water, 0.9 parts of cold water, 3 parts of ethanol and 2.5 parts of glycerol. When dissolved in water, alcohol or with acid treatment produces a lot of heat. The pH of the 0.1 mol / L solution was 13.5. Medium toxic, half lethal dose (rat, oral) 1230mg / kg. Soluble in ethanol, slightly soluble in ether. Has a very strong alkaline and corrosive, Potassium Humate its nature and caustic soda similar.
1, used as a desiccant, absorbent, for the production of oxalic acid and a variety of potassium, but also for electroplating, sculpture, lithography and so on.
2, mainly used for the production of raw materials such as potassium, such as potassium permanganate, potassium carbonate and so on. In the pharmaceutical industry, for the production of potassium boron, spironolactone, heparanol, testosterone propionate and so on. In the light industry for the production of potassium soap, alkaline batteries, cosmetics (such as cold cream, cream and shampoo). In the dye industry, Potassium Humate for the production of dyes, such as reducing blue RSN and so on. In the electrochemical industry, for electroplating, sculpture and so on. In the textile industry, for printing and dyeing, bleaching and mercerizing, and a large number of used for the manufacture of man-made fibers, polyester fiber main raw materials. In addition, it is also used for metallurgical heaters and leather degreasing and so on.
3, chemical raw materials, for medicine, household chemicals and so on.
4, used as analytical reagents, Potassium Humate saponification reagents, carbon dioxide and moisture absorber.
5, the chemical industry for the manufacture of washing soap, shampoo soap, cream, cream, cream, shampoo and other raw materials. The pharmaceutical industry for the manufacture of progesterone, vanillin and other raw materials. The dye industry is used to make melamine dyes. The battery industry is used to make alkaline batteries.
The organization has a burning effect, Potassium Humate can dissolve the protein, the formation of alkaline denatured protein. Solution or dust splashed on the skin, especially splashed into the mucosa, can produce soft scab. The higher the solution concentration, the higher the temperature, the stronger the effect. Splashed into the eye, not only can damage the cornea, but also make the eye deep tissue damage.
The maximum allowable concentration is 0.5 mg / m. Work should be prevented from touching the skin and eyes, such as inadvertently touch, the water can be washed damaged parts, and then wet with 5% acetic acid, tartaric acid, hydrochloric acid or citric acid solution; Potassium Humate such as splashing the eyes, the application of water or saline carefully Slow wash 10 ~ 30 min, and then click on 2% of the carnivacaine or 0.5% of the cardaine solution. Operation should be worn by the fabric of the overall work clothes, wearing rubber gloves, cuffs, aprons, wearing shoes and other labor insurance products, hands should be coated with neutral and hydrophobic ointment.
